We're dividing 71279357 by 80 
Let's see how many times 80 fits into 71279357.

Let's proceed to step 1:
When dividing 7 by 80, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 80

Advancing to step 2:
When dividing 71 by 80, we get 0 with a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Take the next digit (2) from the dividend and append it to 71, then repeat: 712 / 80

Going ahead to step 3:
80 can be fit into 712 8 times, resulting in a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 640 from 712 leaves us with 72.
Append the next digit (7) from the dividend to 72 and continue with: 727 / 80

On to step 4:
727 divided by 80 is 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 89.0
Subtracting 720 from 727 leaves us with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 80

Going ahead to step 5:
80 can be fit into 79 0 times, resulting in a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 890.0
The remainder is 79 after subtracting 0 from 79.
Fetch the next digit (3) from the dividend, attach it to 79 and continue: 793 / 80

Moving on to step 6:
793 divided by 80 is 9 with a remainder of 73.
The number 9 becomes the next digit in our result. 
Result so far: 8909.0
Subtract 720 from 793 to get 73.
Bring next digit (5) of the dividend behind the 73 and repeat the process: 735 / 80

Let's proceed to step 7:
80 can be fit into 735 9 times, resulting in a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 89099.0
Subtracting 720 from 735 leaves us with 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 80

On to step 8:
80 can be fit into 157 1 times, resulting in a remainder of 77.
Record the quotient 1 as the next digit in the result. 
Result so far: 890991.0
If we take 80 away from 157, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 9:
80 can be fit into 770 9 times, resulting in a remainder of 50.
Put 9 as the next digit of the answer. 
Result so far: 890991.9
If we take 720 away from 770, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
80 can be fit into 500 6 times, resulting in a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 890991.96
If we take 480 away from 500, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
The number 80 fits into 200 2 times, leaving a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 890991.962
If we take 160 away from 200, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
80 goes into 400 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 890991.9625
Deduct 400 from 400 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 13:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 890991.9625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 14:
If we divide 0 by 80, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 890991.9625
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 890991.9625 with a remaining 0.0.
